Logging x2go connections?
by Grigory Shamov 04 May '17

04 May '17

Hi All, This perhaps is a trivial question: but is it possible to somehow log/check history of past x2go session on the server? -- Grigory Shamov Westgrid/ComputeCanada Site Lead University of Manitoba E2-588 EITC Building, (204) 474-9625

Shared Folders?
by KARL A. WOELFER 25 Jan '17

25 Jan '17

I am not able to get the basic Shared Folder capability to run. Debian 7 Linux OS on client and server, X2go V 4.0.3.0, and XFCE Desktop. Is there something fundamental preventing this from working? Thanks in advance, - KarlW

Num Lock key in windows agent
by Olivier BILHAUT 24 Nov '16

24 Nov '16

Hi all. First of all, I'd like to congratulate all the contributors for this great work. X2go is a professional class tool for remote desktop. However... I ran into a really special thing using the windows agent in its last version (4.0.5). Sometimes, when you open the session, the "Num Lock" is usable, sometimes not. I mean, sometimes you may push the caps lock button and switch from arrows to Numeric keys, and sometimes the Key Pad is fully unusable. It happens only on windows agent as far as I know. All that I tried did not solve the issue. Did you already encounter that? Thanks. -- OB SySAdmin Fondation Hospitalière de la Miséricorde

x2goclient session icons not working
by Will Wagner 23 Nov '16

Hello, I have upgraded to 4.0.4.0 on win32. It's a minor thing but if I now set a session icon for a connection it is not displayed and I get blank instead. Is there something I need to do to get this to work? Thanks Will

Video

I'm having a lot of trouble getting a gstreamer based video player to work under X2Go. First off it looks like Xv is not supported. Is that something that ever will be? Next thing I'm seeing with the parole player is that the video frame goes black when I pause it. I'm also trying to use the fluendo gstreamer codecs and seeing segfaults (apparently in the fluendo code) when using dragon player to watch videos. I'm running with current nx-libs git from https://github.com/ArcticaProject/nx-libs. EL7 server and client. Any ideas or suggestions? Thanks. -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 http://www.nwra.com

firefox freezing by right-click
by olafs6＠gmx.de 22 Mar '16

22 Mar '16

Hello! I installed the x2goclient in puppy (tahr). When I start a session on my x2go server (Ubuntu 14.04) with this client I have problems with firefox 42.0: - Right-click in Firefox (link, empty space, ...) causes somewhere that the browser for about half a minute to freeze completely -> If I click when he is working again, in the opened context menu on any point, the browser freezes again for the same time again. - Click the top right on "Organize Bookmarks" also causes freezing The whole happens only when using under puppy. Even with use of another x2go server (also Ubuntu 14.04 but Firefox 41.0.1) of puppy from there the same mistake. This happens also when Firefox is directly called x2go, ie without the favored else from me LXDE. When I call a x2go session with a client software on other distributions (Windows, Ubuntu, OpenSuse), the problem does not occur. What here comes with puppy in the way? Greeting, Olaf

Multi monitor not working
by Mario 16 Mar '16

16 Mar '16

Hi everyone, i'm running an x2goserver on a 32bit Kubuntu Trusty Tahr Vmware workstation 9 vm. I have the following debs installed there: ii x2goagent 2:3.5.0.32-0~668~ubu all ii x2goclient 4.0.5.0-0~1099~ubunt i386 ii x2goserver 4.0.1.19-0~1064~ubun i386 ii x2goserver-extensions 4.0.1.19-0~1064~ubun all ii x2goserver-xsession 4.0.1.19-0~1064~ubun all The client is my laptop running 64 bit Kubuntu Trusty Tahr with an extra monitor connected. It has the following packages installed: ii x2goclient 4.0.5.0-0~1099~ubuntu14. amd64 Everything is working as expected but i cannot get any of the methods described in http://wiki.x2go.org/doku.php/doc:usage:multi-display to work. When i stretch my x2go client window over multiple monitors the server sees it as on big screen. It does so regardless of whether i check Xinerama extension or not. My laptop has Xinerama enabled. How would i go about getting this to work? -- Grüße/Regards Mario
